SEAM-PRESSING MACHINE.

SPECIFICATION forming part of Letters Patent No. 643,455, dated February13, 1900. Application filed May 13, 1899. Serial No. 716,647. (Nomodel.)

To aZZ whom, it may concern.-

Be it known that I, CHARLES H. BAYLEY, of Boston, in the county ofSuffolk and State of Massachusetts, have invented certain new and usefulImprovements in Seam-Pressing Machines, of which the following is adescription sufficiently full, clear, and exact to enable those skilledin the art to which it appertains or with which it is most nearlyconnected to make and use the same.

This invention relates to machines for pressing and smoothing the seams,hems, and similar features of leather manufacture, so as to finish orcomplete the same or to suit it for further operative steps in theprocess of manufacture.

It is the object of the invention to so improve seam-pressing machinesand machines for cognate purposes as that they may be used with greaterfacility and to accomplish the work much more expeditiously thanheretofore.

It is also the objectof my invention to render the machines simpler inconstruction and more durable than they have previously been, to the endof securing substantial economy both in construction and use.

To these ends the invention consists of the improved machine hereinafterdescribed in detail and particularly pointed out in the claim.

Reference is to be had to the annexed drawings, and to the lettersmarked thereon, forming a part of this specification, the same lettersdesignating the same parts or features, as the case may be, whereverthey occur.

Of the drawings, Figure 1 is a side elevation of the machine embodyingmy improvements. Fig. 2 is a plan view of the same. Fig. 3 is a verticalsectional View taken on the line 3 3 of Fig. 2.

In the drawings, a designates the bed or base of the machine, from therear standard part b of which there extend forward two arms 0 0, betweenthe ends of which the lever d is fulcrumed on the pin a. The lever 01 isforked at its rear end, and a journal-box f is arranged to reciprocatein said fork, the crank part 9 of a shaft It being arranged to operatein said journal-box and the shaft having a pulley or pulleys i securedto it, by which it is adapted to be rotated. The shaft of course issuitably journaled in the standard b.

j designates the hammer, plunger, or pounder, which is supportedvertically in a suitable guideway in the front end of the lever and-ispressed or held down to normal position by a quite-powerful spring isacting thereon, the nuts Zm, turned on the upper end of the plunger,limiting its downward movement. A washer n, of leather or similarmaterial, is interposed between the support for the shaft of the plungerand the nut Z, so as to cushion the blows between the two.

0 designates the hollow screw-threaded shank of the bed 19, which shankis adapted to be screwed up and down in what is substantially aninteriorly-screw-threaded pinchcollar q, formed on the forward end ofthe base a, so that the bed may be adjusted up and down in its support.Holes r are formed in the periphery of the bed to receive a pin or othermeans for turning the bed to adjust it, and a bolt 8 is extended throughone projection on the pinch-collar and tapped into the other to fix theshank of the bed in position when once it is adjusted to properposition.

t designates the bed-plate, which is provided with a shank a, adapted toextend down through the hollow shank 0 of the bed, so as to maintain itin position. Interposed between the bed 19 and the plate 15 is a washer'0, of leather or other suitable material, to cushion the blow of theplunger j upon the material between it and the bed-plate. The shank u ofthe bed-plate will be sufficiently loose in the hollow shank to permitthe bedplate t to turn with the material being operated upon.

In the operation of the machine, a belt being applied to the pulley t'the leverd will be oscillated quite rapidly and the plunger will ofcourse be operated in like manner, so that seamed material passedbetween the plunger j and the'bed-plate i will be acted upon and poundedor smoothed down with great nicety, and if thick places should beencountered the spring pressing down the plunger will of course yield,so that the plunger will not act with too great energy or force. Asbefore stated, in turning material being operated upon by the plungerthe fact that the bed-plate t is constructed to turn on its shank willgreatly facilitate the operation.

The vertical adjustability of the bed is for the purpose of suiting themachine to varying thicknesses of leather.

Provision is made, it will be seen, so that the bearings of all themovable parts may be freely lubricated.

The great advantages of this machine are its simplicity, the readinesswith which it may be adjusted, the facility with which the work of theseam-pressing may be performed, and its strength and durabilitygenerally. The cushioning of both the plunger and the bed-plate arethings that cushion the violence of the blows and deaden the noise, sothat it may not be objectionable.

Having thus explained the nature of the invention and described a way ofconstructing and using the same, though without attempting to set forthall of the forms in which it may be made or all of the modes of its use,it is declared that what is claimed is- In a machine of the characterdescribed,

the combination of a lever having atubular head; a hammer having a stemextending through said head; a spring surrounding the stem within thehead between shoulders of the latter and the stern; a stop-nut on thestem above the head; and sound-deadening or cushioning materialinterposed between said nut and the head.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 18th day of
